2 Safety and maintenance guidelines

Important safety information

A power cord is included with the display. If another cord is used, use only a power source and connection

appropriate for this display.

WARNING! To reduce the risk of electric shock or damage to the equipment:

• Do not disable the power cord grounding feature. The grounding plug is an important safety feature.

• Plug the power cord in a grounded (earthed) outlet that is easily accessible at all times.

• Disconnect power from the product by unplugging the power cord from the electrical outlet.

For your safety, do not place anything on power cords or cables. Arrange them so that no one can

accidentally step on or trip over them. Do not pull on a cord or cable. When unplugging from the electrical

outlet, grasp the cord by the plug.

To reduce the risk of serious injury, read the Safety and Comfort Guide. It describes proper workstation,

setup, posture, and health and work habits for computer users, and provides important electrical and

mechanical safety information. This guide is located on the Web at

www.hp.com/ergo and/or on the

documentation disc, if one is included with the display.

CAUTION: For the protection of the display, as well as the media player/computer, connect all power cords

for the media player/computer and its peripheral devices (such as a display, printer, scanner) to some form of

surge protection device such as a power strip or Uninterruptible Power Supply (UPS). Not all power strips

provide surge protection; the power strips must be specifically labeled as having this ability. Use a power

strip whose manufacturer offers a Damage Replacement Policy so you can replace the equipment, if surge

protection fails.

Use the appropriate and correctly sized furniture designed to properly support your display.

WARNING! Displays that are inappropriately situated on dressers, bookcases, shelves, desks, speakers,

chests, or carts can fall over and cause personal injury.

Care should be taken to route all cords and cables connected to the display so that they cannot be pulled,

grabbed, or tripped over.

CAUTION: Do not place the device in a location where water may drip and/or splash on the device.

Do not place an object that contains water, such as a flower vase, on the device.

Maintenance guidelines

To enhance the performance and extend the life of the display:

●

Do not open the display cabinet or attempt to service this product yourself. Adjust only those controls

that are covered in the operating instructions. If the display is not operating properly or has been

dropped or damaged, contact an authorized HP dealer, reseller, or service provider.

●

Use only a power source and connection appropriate for this display, as indicated on the label/back

plate of the display.

●

Be sure the total ampere rating of the products connected to the outlet does not exceed the current

rating of the electrical outlet, and the total ampere rating of the products connected to the cord does

Important safety information 3

not exceed the rating of the cord. Look on the power label to determine the ampere rating (AMPS or A)

for each device.

●

Install the display near an outlet that you can easily reach. Disconnect the display by grasping the plug

firmly and pulling it from the outlet. Never disconnect the display by pulling the cord.

●

Turn the display off when not in use. You can substantially increase the life expectancy of the display by

using a screen saver program and turning off the display when not in use.

CAUTION: Burn-in or image sticking might occur on displays which display the same static image on

the screen for prolonged periods of time. To avoid burn-in or image sticking and to prolong the life of

the display, you should activate one of the four ISM selections in the OSD, activate a screen-saver

application, periodically cycle between static information and moving images, or turn off the display

when it is not in use for prolonged periods of time.

●

Slots and openings in the cabinet are provided for ventilation. These openings must not be blocked or

covered. Never push objects of any kind into cabinet slots or other openings.

●

Do not drop the display or place it on an unstable surface.

●

Do not allow anything to rest on the power cord. Do not walk on the cord.

●

Keep the display in a well-ventilated area, away from excessive light, heat or moisture.

●

When removing the display base, you must lay the display face down on a soft area to prevent it from

getting scratched, defaced, or broken.

Cleaning the display

1. Turn off the display and unplug the power cord from the back of the unit.

2. Dust the display by wiping the screen and the cabinet with a soft, clean antistatic cloth.

3. For more difficult cleaning situations, use a 50/50 mix of water and Isopropyl alcohol.

CAUTION: Spray the cleaner onto a cloth and use the damp cloth to gently wipe the screen surface. Never

spray the cleaner directly on the screen surface. It might seep behind the bezel and damage the electronics.

CAUTION: To clean the display screen or cabinet, do not use cleaners that contain any petroleum-based

materials such as benzene or thinner or any volatile substance. These chemicals might damage the display.

Mounting on a wall

For proper ventilation, allow a clearance of 10 cm on each side and from the wall. Detailed installation

instructions are available from the manufacturer of the mounting equipment..

If you intend to mount the display to a wall, attach a wall mounting interface (optional parts) to the back of

the set.

When you install the display using a wall mounting interface (optional parts), attach it carefully so it will not

fall.

1. Use a wall mount and screws in accordance with VESA Standards.

If you use screws longer than the VESA standard, the display might be damaged internally.

If you use improper screws, the product might be damaged and drop from mounted position. In this

case, HP is not responsible for damage.

2. Use VESA standard as follows:

●

785 mm (31 inch) or greater

●

Fastening screw: Diameter 6.0 mm x Pitch 1.0 mm x Length 10 mm

CAUTION: Disconnect the power cord first, and then move or install the display. Otherwise electric shock

may occur.

If you install the display on a ceiling or slanted wall, it may fall and result in severe injury.

Use an authorized HP wall mount and contact the local dealer or qualified personnel.

Do not over tighten the screws as this may cause damage to the display and void your warranty.

Use the screws and wall mounts that meet the VESA standard. Any damages or injuries by misuse or using an

improper accessory are not covered by the warranty.

NOTE: The wall mount bracket is optional. You can obtain additional accessories from your local dealer.

The length of screws may differ depending on the wall mount. Be sure to use the proper length.

For more information, refer to the manufacturer’s instructions supplied with the wall mount.

8 Chapter 3 Assembling and preparing

Securing the product to a wall (optional)

1. Insert and tighten eye-bolts or product brackets and bolts on the back of the product. If there are bolts

inserted at the eye-bolts position, remove the bolts first.

NOTE: Eye-bolts or wall brackets are not included with the display.

2. Mount the wall brackets with the bolts to the wall. Match the location of the wall bracket and the eye-

bolts on the rear of the product.

3. Connect the eye-bolts and wall brackets tightly with a sturdy rope. Make sure to keep the rope

horizontal with the flat surface.

CAUTION: Make sure that children do not climb on or hang on the product.

NOTE: Use a platform or cabinet that is strong and large enough to support the product securely.

Brackets, bolts and ropes are optional. You can obtain additional accessories from your local dealer.

WARNING! If a product is not positioned in a sufficiently stable location, it can be potentially hazardous due

to falling. Many injuries, particularly to children, can be avoided by taking simple precautions such as:

●

Using cabinets or stands recommended by the manufacturer of the product.

●

Only using furniture that can safely support the product.

●

Ensuring the product is not overhanging the edge of the supporting furniture.

●

Not placing the product on tall furniture (for example, cupboards or bookcases) without anchoring both

the furniture and the product to a suitable support.

●
